Re: Industrial open screw compressor running with R-600 - butane
Butane as a refrigerant works like any other hydrocarbon refrigerant , for eg propane , propylene etc.
Just check the compatibility of lube oil while selecting refrigerant . Normally you can use CPI oil with 68 CP for propylene and CPI oil with 150 CP viscosity for propane.
Butane is flammable and therefore check the motor . it shall be at least Ex NA.
All the instruments shall be at least Exd or Exi but it depends.
Butane as a refrigerant is less costly as compared to other refrigerants like R 404 A etc .
Disadvantage is basically due to flammable nature of refrigerant .You are bound to use flameproof instruments , stringent motor requirement etc.
